Eaton PDUB151U Hot-Swap Bypass Power Distribution Unit PDU
Overview
The Eaton Tripp Lite Series PDUB151U is a 1U horizontal rackmount single-phase hot-swap power distribution unit (PDU) featuring an integrated manual bypass transfer switch. Engineered for server environments, data centers, and network closets, this specialized hardware enables zero-downtime maintenance and hot-swapping of connected 100V to 125V UPS systems. System administrators deploy this unit to isolate failing or end-of-life battery backups without interrupting operational power to active computing equipment.
The electrical architecture operates via dual NEMA 5-15P input cables×one dedicated to the host UPS output and the other connected directly to secondary utility grid power. Under normal operations, the mechanical selector switch routes conditioned energy from the UPS across its six NEMA 5-15R outlets. When the manual switch is turned to the bypass position, internal contacts transparently shift the electrical load onto the utility grid circuit in 0 milliseconds, permitting safe physical replacement or servicing of the battery backup system.
Efficiency management is enhanced by a built-in green ECO power-saving mode. When toggled, the PDU monitors power consumption at the designated master 5-15R receptacle; if the master device shuts down or slips into a low-power state, five secondary controlled outlets are automatically de-energized to reduce phantom load overheads. Constructed inside a rugged all-metal 1U enclosure, the PDUB151U accommodates flexible horizontal placement inside standard 19-inch EIA-compliant enclosures or secure mounting directly to masonry structures.
Key Features
Manual transfer switch shifts loads immediately to isolate connected UPS modules.
Dual NEMA 5-15P inputs ensure distinct access paths to backup and utility power.
Optional ECO switching mechanism de-energizes secondary ports to cut idle waste.
Standard 1U hardware forms fit low-profile deployment footprints inside server racks.
Robust all-metal chassis withstands continuous operational thermal stress.
